Advatech Designs Zero Liquid Discharge Systems as well as Scrubbers:
Advatech is a joint venture between URS and Mitsubishi. They have sold many scrubber systems in the U.S. Mitsubishi is the largest scrubber supplier world wide. They are now emphasizing their water management abilities including zero liquid discharge.
Advatech Water Management: As concerns mount over the quality and quantity of our water supply, regulatory limits on water usage and discharge grow more stringent. In many instances, water usage brings with it a significant expense, and going to Zero Liquid Discharge (ZLD) is either a necessity or an expected near-term requirement.
ADVATECH has designed wet FGD systems for chloride concentrations up to 50,000 ppm so that the only source of purge is the free moisture in the disposal-grade gypsum. However, this approach can incur a hefty cost in the form of materials of construction and decreased limestone reactivity. To minimize cost, we have been at the forefront in developing low-capital technologies capable of eliminating liquid discharge from wet FGD while maintaining chloride levels in a reasonable range, all this without the need for an expensive and complicated wastewater treatment process.
We also have technologies designed to capture heat from the air-heater-outlet flue gas, prior to the wet FGD, to dramatically reduce the amount of water lost to evaporation and hence required by the wet FGD. The heat removed can either be recovered within the steam cycle, resulting in boiler efficiency improvements, or used to heat the effluent from the wet FGD, eliminating a wet stack.
Wastewater Evaporation System (WES) involves the direct injection of the
required liquid purge stream from the wet FGD process into the flue gas ductwork
through dual-fluid spray nozzles. Filtrate from the FGD process is pumped to an
array of nozzles installed upstream of the particulate control device where it
combines with compressed air to generate a fine mist that flash
evaporates. The chlorides and other dissolved species form solid particulate that is removed from the flue gas with the fly ash in the existing particulate control device. For a typical
installation, the WES process results in less than a 5% increase in particulate loading. The WES offers a low-capital means of eliminating a wet FGD purge stream. Operating costs are minimal—mainly for the power required to operate the air compressors. ADVATECH (as MHI) has 10 commercial installations of the WES technology and 50 years of cumulative operating experience.
